Name: Wild garlic, Allium vineale
L.,
Other Names: ail des vignes, Field garlic,
Scallions, Wild onion
Family: Lily Family (Liliaceae)
General Description: Perennial, reproducing
by seed and by 3 kinds of bulbs.
Wild garlic (left to right - base of mature plant, hard-shelled
bulbs, young plants, germinated bulblets, aerial bulblets, (top,
right) kernels of wheat).
Wild garlic. A. Base of plant. B. Top of plant. C. Hard-shelled bulbs. D. Aerial bulblet.
Stems & Roots: Young plants very
grass-like in appearance with erect, slender, rounded or flattened,
smooth-textured leaves; flowering stems erect, mostly unbranched,
30-100cm (12-40in.) high, round, solid or sometimes hollow; stem
leaves with a tubular sheath and long slender blades; the blades
channeled or flattened near the base, thicker and nearly round towards
the tip.
Flowers & Fruit: Flowers in a
head-like cluster (umbels) at the tip of the stem, each cluster
at first surrounded by a papery bract or spathe; each flower with
6 small petals, greenish to white, pink or purplish-red, 6 stamens
and 1 pistil, but usually most or all flowers replaced by small
bulblets; bulblets about 3-5mm (1/8-1/5in.) long and closely resembling
but much smaller than the bulbs normally produced in the base of
the plant. Base of plant usually producing 2 kinds of bulbs, a soft-shelled
bulb that is teardrop-shaped, usually 8-17mm (1/3-2/3in.) long and
white, and hard-shelled bulbs which are light brownish, about the
same size but distinctly flattened on 1 side and with a thick, hard
shell. The whole plant has a very strong garlic odour. The flower
or bulblet heads are produced during July and August and when growing
in fields of wheat, oats or barley, may be harvested with the grain.
They shatter readily into individual bulblets that cannot easily
be separated from the cereal grain because of their size and shape.
Habitat: Wild garlic occurs only in
the Niagara peninsula of southern Ontario, growing in fields, vineyards,
roadsides and edges of woods. Other kinds of Wild onion also grow
in Ontario but their aerial bulblets, if produced at all, are two
to three times larger than those of Wild garlic, and hardshelled
bulbs are rarely produced in the bases of these plants.
Similar Species: It is distinguished by
its slender erect stems and leaves, its soft, smooth texture, its
cluster of little bulblets instead of flowers at the tips of stems,
its hard-shelled bulbs produced around the mother bulb in the ground,
and the strong garlic odour in all parts of the plant.
